Application metrics

Knowing an application's configuration isn’t enough to effectively operate and
manage it. Consider that a well-designed application will have as few
configurable parameters as possible. As an operator, you may find yourself
wanting to know more about the resources that an application in your model
consumes and provides -- resources such as:

Storage GiB used

Number of user accounts

Number of recently active users

Active database connections

Juju Metrics complete the operational picture with application observability;
by modeling, sampling and collecting measurements of resources such as these.
Juju collects application metrics at a cadence appropriate for taking a
model-level assessment of application utilization and capacity planning.

There are many instrumentation and time-series data collection solutions
supporting devops. Juju’s metrics complement these fine-grained, lower-level
data sources with a model-level overview -- a starting point for deeper
analysis.
